ONE FAT CAT
Announced at SHOT 2023, the YHM Fat Cat (and Cat's Ass) are short, fat, and offer the performance of a full-sized 5.56 silencer in a compact package. Yankee Hill Machine designed a silencer with the length of a shorter "K" can at 4.5" but added volume through a larger diameter. The extra girth keeps things quiet, but the small size still allows for maneuverability. The rear portion is stepped down, allowing for easy mounting under most handguards and providing a seamless look when mounted to the host.
This full-auto-rated feline is available in two versions. The Standard Fat Cat will be family-friendly with a traditional front cap. The Cat's Ass takes it up a notch for those more adventurous shooters. While functionally the same, with the Cat's Ass, you'll be expelling your projectile in the same area your little friend expels his. The Cat's Ass has a limited edition front cap engraved with what you would expect.
The Fat Cat can be used on all 5.56 NATO barrels with a length of 10" or longer.
